.NET Explorer enables developers and testers to explore the TCP/HTTP network traffic that is sent and received with each Web service and .NET Remoting call. Such information can be helpful to developers in seeing how large objects are serialized in XML when they are sent. It is also helpful to testers in load-testing scenarios.
With Web service calls, which are generally XML over HTTP, the actual content of HTTP headers from the requests and responses is displayed.
Hex View - Displays traffic data in binary (hexadecimal) view. This is useful when exploring the .NET Remoting binary protocol.
